How can I file a divorce against my husband?

I’m 43 years old female. I got married on 25 July 2015. I don’t have any kids. Living separately since beginning because husband left me alone in another city and didn’t stay with me and was expecting only salary. My parents tool care of me in emergency every time. Husband is impotent and greedy of money. Mental, physical and financial harassment is there. He expects money from me. If I’m working in MNC then on which ground I should file maintenance under case section 25 of HMA? I have personal loan and no permanent job, also I’m not medically fit due to spondylitis problem at severity. Lost my parents in 2021. No support from family and one dependent younger brother is there. I want divorce now. He is in hardware business and having own shop and house in Delhi. Please suggest.
